Density of water in SI units over the range 0-40 C

A table of water densities over the range 0-40°C, expressed in SI units (kg m-3, i.e. 10-3 g cm-3), is presented. The table has been obtained by applying the relationship 1 litre (1901) = 1.000 028 cm3 to new values derived from an improved combination of the observations of Chappuis and Thiesen on the dilatation of water, no modern determinations being, or likely soon to be, available. The table relates, as is usual, to air-free water, but the effect of air, which is small, is indicated.
